JOINT FOR BRACELETS- To all who/1L 7'15 m/ay concern:

Be it known that I, NILS C. WALLENTHIN, a citizen. of the United States, residing at CentralFalls, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Joints for Bracelets, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to joints for bracelets or similar articles, and has for its object to provide a neat, efficient, durable, and practical joint that is simple of construction.

A further object of the invention is to provide a joint that may be readily concealed in the tubing of the bracelet and one that will allow the two parts of the same to be drawn apart or opened to the desired extent and brought back into position again, rendering the line of separation practically invisible.

The invention is fully set forth in this specification, and more particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 shows the bracelet in its closed position at approximately its natural size with a portion broken away illustrating the joint in section. Fig. 2 is a greatly-enlarged view showing a portion of the tubing with the members of the joint partly in section in the closed position. Fig. 3 illustrates the joint in the position taken when the bracelet is open. Fig. 4 is a detail perspectiveview of the tongue member of the joint. Fig. 5 is a detail perspective view of the grooved member of the joint. Fig. 6 is a perspective view of the link connecting the tWo said members. Fig. 7 shows a side elevation and an end elevation, respectively, of the said link. Fig. 8 is a perspective view of the pin that holds the link to the tongue member. Fig. 9 is a sectional view of said tongue member. Fig. 10 is a sectional elevation of the grooved member. Fig. 1 1 is a section on line 11 11 of Fig. 10, showing the groove in said grooved member. Fig. 12 is a modification showing the tongue member as being jointed.

Referring to the drawings, at 1 is the tubing of the bracelet, which tubing may be made as ornamental as desired and bent into a form to fit loosely about the wrist. In

bracelets of the character illustrated it is customary to divide the same into two parts and hinge said parts together, so that they maybe Specification of Letters Patent.

separated or opened to allow of the wrist passing through, after which the parts are closed together and locked. The point of separation, at 2, is where the joint is formed, while directly opposite, at 3, is the opening-point, at which point the two parts are brought together and locked by any suitable locking device.

My improved bracelet-joint is constructed of two interlocking membersnamely, a tongue member 4, that is inserted and fixed into one portion of the tubing, and a grooved member 5, fixed in the end of the opposite end of the tubing. These members are loosely connected together by a link 6 to work one within the other. This link 6 is provided with a bar 7 at right angles to the body or shank of the same across its upper end. When this link is in position, its shank 6 extends down through the slot 8 in the grooved member and the cross-bar 7 engages the little recess 9 in the upper side of said member. The lower end of this link 6 is pivoted in the slot 10 of the tongue member by the pivot-pin 11. The tongue portion 12 of this member 4 is arranged to slide freely in the groove 13 of the grooved member, which groove is cut out somewhat in a circular form (see Fig. 10) to allow of the necessary longitudinal movement of the said tongue therein when the bracelet is opened and closed. This groove and tongue construction provides this joint with the necessary means for resisting lateral strains, and the link provides the necessary freedom to admit of the joint being opened and to insure the return of the same to the proper position.

The outer end of the grooved member is provided with a hooked nose or end piece 14, that is adapted to hook over and slide on the slanting wall or surface 15 of the protuberance 15 in the neck of the tongue member and serves to draw the joint and parts of the tubing closely together when the bracelet is closed, firmly locking the same in that position. When the bracelet is opened, the members take the position illustrated in Fig. 3, the link 6 drawing the end 16 of the tongue up against the bottom of the groove 13, forming a stop to limit the opening of the bracelet. The tongue 12 may be hinged, as shown in Fig. 12, if desired, to render the joint more flexible.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is 1. A bracelet constructed of tubing and having a joint formed of two separate hinge members, and said members having engaging means for positively drawing the hinged por tion of the bracelet tightly together as said bracelet is closing.

2. A bracelet constructed of tubing and having a joint formed of two separate members fixed into the ends of said tubing, and said members having means whereby one of said members engages the other to positively draw the hinged portion of the bracelet tightly together as said bracelet is closing.

3. A bracelet, constructed of tubing, and having a joint formed separate and inserted into said tubing said joint being composed of two interlocking members and a link connecting said members together.

4. In a bracelet, a joint composed of two interlocking members, a pivoted link loosely connecting said members together, and means for drawing the joint tightly together when the bracelet is closed.

5. In a joint for a bracelet, a tongue member, a grooved member, the tongue in said first-named member adapted to engage and reciprocate in the groove in said secondnamed member, and a link connecting said members together.

6. A bracelet constructed of tubing and having a joint comprising two interlocking members, a swinging link connecting said members together, and means in said members whereby the ends of said tubing will be brought tightly together when the bracelet is closed.

7. In a joint for a bracelet, a tongue member, a grooved member, the tongue in said first-named member adapted to engage and reciprocate in the groove in said secondnamed member, a link connecting said members together, means in said members whereby they will be drawn together when closed, and means in said members for limiting the extent of opening of the hinge.

8. A bracelet constructed of tubing and having a joint comprising a member fixed into one end of the tubing, a second member fixed into another end of the said tubing,

means including a swinging link for connecting these two members together, and means in said members whereby the ends of said tubing will be drawn together when the bracelet is closed.

9. A bracelet constructed of tubing and having a joint comprising a grooved member fixed into one end of the tubing, a tongue member fitted into another end of said tubing, said tongue being adapted to engage and reciprocate in the groove in said grooved member, a swinging link adapted to connect these two members together, and means in said members whereby the ends of said tubing will be brought tight together when the bracelet is closed.

10. A bracelet constructed of tubing and having a joint comprising a member fixed into one end of the tubing, a second member fixed in another end of the tubing, means including a swinging link for connecting these two members together, a hooked end piece in one of said members, a protuberance on the other member having a wall slanting from its apex away from the end of the tube, whereby said hooked member is adapted to hook over and engage said slanting wall to draw the two members together while the bracelet is being closed.

1].. A bracelet constructed of tubing and having a joint comprising a grooved member fixed into one end of the tube, a tongue member fitted into an adjacent end of said tube, said tongue being adapted to engage and reciprocate in the grooved portion of said grooved member, a swinging link adapted to connect these two members together, the grooved member having a hooked end, a protuberance on the other member having a wall slanting from its apex away from the end of the tube whereby said hooked end is adapted to engage said slanting wall to draw the two members tightly together when the bracelet is being closed.

In testimony whereof I affix my signature in presence of two witnesses.
